In addition to the information given, it is possible to surface grind on a vertical mill. There are quite a few small mills which are pretty rough on facing and, of course, there is quite a lot of inaccuracy generated by flycutting. Believe me, the old English model engineering press was full of it at one time.

Buhrstone mills are one of the oldest types of mills used for grinding grains and hard materials. Disk attrition mills are modern versions of the ancient Buhrstone mill. Vertical shaft mills work on the same principal as VSI crusher, with a rotor on a vertically mounted shaft using centrifugal force to throw the media against a wear plate.

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...

Windmills were initially used for milling, hence 'mills'. A large round heavy stone is turned by the wind powered wings and grinds against another stationary stone beneath it. The grain or corn is fed between the stones and ground into flour. It's dusty work, you definitely wouldn't want to live in a flour grinding mill.
